First, raising a lonely monkey requires registration. All monkeys need it, no matter what kind you raise. This is under the jurisdiction of the Jungle Public Security Bureau, which is composed of the national forestry department and public security agencies and has criminal and administrative law enforcement powers. If you don't register, if you keep it privately, you may be caught. In short, it is illegal to buy, capture, trade, and raise monkeys without permission.
Secondly, monkeys do not take long to be tamed and are very wild. Monkeys have been tamed in large numbers and have begun to become pets, and the world is only so small. Therefore, the taming of monkeys is not perfect yet. Although some monkeys are very docile, they are still particularly violent. If you don’t believe it, you can save your mother from “the scratches and bites of pet monkeys”. Really, whoever sees it will know it. If you are frightened by it, any monkey, especially when it is in heat, will become irritable. Aggressive and quite terrifying.
